Disk device for maintaining a horizontal state of a front edge portion of an elevating frame

Abstract

A disk device comprising: a turn table, a clamp head, a spindle motor and an elevating frame, wherein the turn table and the clamp head fixed to a driving shaft of the spindle motor disposed at a front end of the elevation frame disposed in a direction along a diagonal line inside of the disk device, and means for rocking a front end of the elevating frame up and down to clamp an optical disk by the clamp head and to hold the optical disk on the turn table or to release the clamping state of the held optical disk, wherein when the front end of the elevating frame descends, a horizontal state of a plane orthogonal to a diagonal line of the elevating frame is held, or either the left side or right side of the front end of the elevating frame is more inclined than the other.

1. A disk device comprising: a turn table;
 a clamp head; 
 a spindle motor; 
 an elevating frame including a front end, a rear end, and a rear end portion; 
 wherein the turn table and the clamp head are fixed to a driving shaft of the spindle motor that is disposed adjacent to the front end of the elevating frame; 
 means for rocking the front end of the elevating frame up and down to clamp an optical disk by the clamp head and to hold the optical disk on the turn table or to release the held optical disk; 
 wherein when the front end of the elevating frame descends, a horizontal state of a plane of the front end of the elevating frame is held parallel to the optical disk; and 
 wherein the elevating frame is movably supported by a chassis along at least one axis and is rocked on a different axis being positioned at the rear end portion, and where the different axis is non-parallel with the at least one axis. 
 
   
   
     2. The disk device according to  claim 1 , wherein the rear end of the elevating frame is supported in a buffering manner. 
   
   
     3. The disk device according to  claim 1 , wherein the elevating frame is further supported by at least one supporting tongue piece that comprises at least part of the at least one axis. 
   
   
     4. A disk device comprising:
 a front bezel; 
 a slot in the front bezel for receiving an optical disk; 
 an elevating frame that supports a turn table, a clamp head, and a spindle motor that selectively engages the optical disk, wherein the elevating frame has a first end adjacent the slot and a second, free end adjacent to the clamp head; 
 a first driving pin coupled to the elevating frame at a first distance from a supporting axis of the elevating frame and a second driving pin coupled to the elevating frame at a second, greater distance from the supporting axis of the elevating frame than the first distance; and 
 a pair of cam grooves that engage the first and second driving pins to move the elevating frame up and down so that a plane of the second, free end of the elevating frame remains parallel to the optical disk when the elevating frame moves up and down; 
 wherein the first end of the elevating frame is supported by first and second supporting tongue pieces respectively deposed at first and second places along the front bezel so that the first and second places are rocking support points and define the supporting axis of the elevating frame; 
 wherein a ratio of a vertical movement distance of the first driving pin to the first distance is greater than a ratio of a vertical movement distance of the second driving pin to the second distance; and 
 wherein when the second, free end of the elevating frame descends, the second supporting tongue piece located at the second driving pin side of the elevating frame is slightly floated and the first supporting tongue piece located at the first driving pin side of the elevating frame is slightly sunk. 
 
   
   
     5. The disk device according to  claim 4 , wherein the first end of the elevating frame is supported in a buffering manner. 
   
   
     6. A disk device comprising:
 a front bezel including a slot in the front bezel for insertion and removal of an optical disk; 
 a turn table; 
 a clamp head; 
 a spindle motor; 
 an elevating frame including a front end, a front end portion, a rear end, and a rear end portion; 
 means for rocking the front end of the elevating frame up and down to clamp the optical disk by the clamp head and to hold the optical disk on the turn table or to release the clamped optical disk; 
 wherein the turn table and the clamp head are fixed to a driving shaft of the spindle motor that is disposed at the front end portion of the elevating frame; 
 wherein the elevating frame has a length that is oriented along a diagonal angled with respect to the front bezel and is supported substantially along the front bezel; and 
 wherein when the front end of the elevating frame descends, the means for rocking rocks the elevating frame about a rocking axis substantially orthogonal to the length of the elevating frame at the rear end portion of the elevating frame and a horizontal state of a plane of the front end of the elevating frame is held parallel to the optical disk. 
 
   
   
     7. The disk device according to  claims 6 , wherein the rear end of the elevating frame is supported in a buffering manner.
